environmental research web: Trading long-term carbon dioxide removal futures would be 'reckless'

On Coffman/Lockley (2017). "So there is potential to create a "futures" market for carbon dioxide removal, allowing investors to sell carbon dioxide removal credits to polluting companies today, based on the assumption that the investors will be able to deliver the technology at a lower price in the future. In most instances, however, trading long-term carbon dioxide removal futures would be a reckless manoeuvre, according to an investigation of whether this is a realistic way to organize risk transfer for this particular market."

Ellery, Alex (2016): Low-Cost Space-Based Geoengineering. An Assessment Based on Self-Replicating Manufacturing of in-Situ Resources on the Moon

Ellery, Alex (2016): Low-Cost Space-Based Geoengineering. An Assessment Based on Self-Replicating Manufacturing of in-Situ Resources on the Moon. In: International Journal of Environmental, Chemical, Ecological, Geological and Geophysical Engineering 10 (2), S. 278–285.

"Here, a space-based approach is presented that is modest in cost, fully controllable and reversible, and acts as a natural spur to the development of solar power satellites over the longer term as a clean source of energy. The low-cost approach exploits self-replication technology which it is proposed may be enabled by 3D printing technology."

Salon: Engineering the atmosphere: Is it possible? And would it prevent catastrophe, or cause it?

"It may be possible to alter the atmosphere and create "global dimming." But is the solution worse than the problem."

Project: Beyond Carbon Neutral (University of Michigan)

"Beyond Carbon Neutral is designed to take the necessary steps to develop this crucial area and raise its profiltion at local and global levels. The Energy Institute has worked with over 60 faculty to develop more than 45 inventive research proposals investigating different aspects of CDR. These research activities fall into three overlapping areas: the biosphere, technology, and human systems. Some Beyond Carbon Neutral research activities fall clearly into one research area, while others bridge the conceptual divides that too often limit the scope and ambition of academic research."

Honegger, Matthias; et al. (2017): Climate change, negative emissions and solar radiation management: It is time for an open societal conversation

Honegger, Matthias; Münch, Steffen; Hirsch, Annette; Beuttler, Christoph; Peter, Thomas; Burns, Wil et al. (2017): Climate change, negative emissions and solar radiation management: It is time for an open societal conversation. Risk-Dialogue Foundation St.Gallen; Swiss Federal Office for the Environment (White Paper).

"An open societal conversation needs to address the emerging topic of climate engineering. The possibility of novel approaches to limit climate risk is increasingly discussed among researchers and carries important social, environmental, and ethical implications and risks. Tough questions on governance, protection against misuse, costs, benefits and risks of both climate change and climate engineering demand an open conversation in order to build a robust basis for reasoned and democratic decisions in Switzerland and indeed the whole world."

Johnson, Katelyn; et al. (2017): Carbon Dioxide Removal Options. A Literature Review Identifying Carbon Removal Potentials and Costs. (Master Thesis)

Johnson, Katelyn; Martin, Derek; Zhang, Xilin; DeYoung, Carissa; Stolberg, Andrew (2017): Carbon Dioxide Removal Options. A Literature Review Identifying Carbon Removal Potentials and Costs. (Master Thesis). University of Michigan.

"The biggest takeaways from the literature review is that this set of CDR options offer enough removal potential to warrant equal consideration to other emission reduction measures, all options face limitations and uncertainties so a diverse portfolio of options should be pursued, and implementation should occur in a staged manner, in which options are implemented as they become feasible."

Daily Iowan: Art colony wraps with geo-engineering

"“In collaboration with the engineering department at the University of Iowa [Rick Fosse and Jeff Crone], I have developed a printmaking-based iron-fertilization prototype that employs the industrial debris left over from demolition efforts at the nearby Sinclair meatpacking facility. This prototype will convert the site’s industrial waste into iron sulfate, the primary ingredient in ocean fertilization geo-engineering projects. As such, the site-remediation effort for this urban brownfield will be built into the creation of the monument itself.""
